Greenville SC | Ours at school would overheat idling on the ground if you were not careful. That was also turning a prop pushing a tremendous amount of air over it. Those are also prone to hydro locking from oil draining into the lower cylinders, I don't see anyway to turn it over by hand. What would really be bad butt is a rotary radial, pretty flipping dangerous for that application. http://youtu.be/-UBAukXPD-0

Northfield Mn | The centrifugal forces would make that extremely hairy to actually ride.
Even the BMW flat engines were weird to ride and there is nowhere near the amount of weight being slung around like there would be on that.
I'll parrot the overheating issue, aircraft engines need airspeed more than just prop wash for cooling.
I'm boatless.

I'm not sure about that - it's just the crank/cam that is spinning - the pistons are still just going up and down in the cylinder sleeves. ![[Linked Image]](http://bozgo.com/wp-content/uploads/2012/12/How-Things-Work-6.gif) But...here's probably a better idea from that perspective (the cooling issue gets worse). You probably also want to put some tape or velcro around your left pant leg.  ![[Linked Image]](http://thekneeslider.com/images/radialmotorcycle2.jpg) ....man, are we off topic.

Northfield Mn | I understand the concept. But there's still going to be way more mass there than a flat four beemer, and those cylinders aren't going anywhere either.
I'm boatless.

| Encountered? No, no, no. Well past encountered...
Back on topic... I had an outstanding, long weekend at Madcatter. But, I don't care what the docs say, or what titles people have. If you think for one half of one second that Larry isn't in charge, I can't help you. Let's just say, they all know who signs their paychecks, or at least keeps funds in the account.

Mike Mike, We're just a couple out of thousands of a-holes with an opinion. It really doesn't matter what you or I think. I don't have anything invested in it other than a t-shirt and the time I spend viewing. Enjoy commenting here once and a while but certainly not going to argue about it.
Have Fun

South Carolina | US Sailing and America’s Cup Launch New ‘Start Sailing’ WebsitePORTSMOUTH, R.I. (May 6, 2013) – US Sailing, the national governing body of the sport, has joined forces with the pinnacle event in sailing - the iconic America’s Cup - to introduce, inform and educate a new generation of sailors. The new website at www.startsailing.org offers visitors an exciting and easy-to-follow introductory view of sailing, including information on the various types of sailboats, the basics of sailing, tips on how to get started and find access to boats and lessons, as well as other ways to get involved. On a side note, US Sailing updated the multihull detail on www.startsailing.org (presumably from my email). They removed the negative stuff, added a little, and now it doesn't make much sense (cruising multihulls are easy to launch from the beach?)...whatever

I bet MOST of the world will understand that because they have seen the glossy bare boat advertisments of a cruising mulit tied up to a tree on some island resort beach...
Of course it is beach launched... You walk off the beach and launch your Gunboat.... QED!

South Carolina | And I'm still not sure how the text is broken down into "What" and "why" and what follows.

Portland, Maine | All those recommendations amount to "Sail 66% of the races that you were planning on sailing" Bullocks. I hope my tickets are redfundable in case its blowing 23.5knots. | | | Re: AC72 Oracle Team USA Spaceship has landed

On the Water | Hopefully, things are getting back to sailing. We should see ETNZ, Oracle, and Luna Rossa AC72 teams on the bay today. Let the games begin.

| Some interesting stuff in there. Capsize, and it's officially game over... Like you could recover a 72, and start racing in hopes of the other guy flipping? These aren't Hobie 16s... I'm pretty sure that no one sailing these is thinking about the race while the boat is on its side, and it's not like the other boat is going to be able to offer more help than the RIBs. Mike | | |
